These internal Microsoft videos, provided to Wired by a person who
worked on the project, show focus groups testing the ill-fated
Kin. According to our source, these are pre-production models that
changed very little from the shipping product, although
“performance improved some prior to shipping.” Watch them, and
you can readily see why the project tanked: Kin phones just
weren’t usable. Or, as our source described them, they were a
“pile of shit.”
